The application provides a longitudinal control method and device of an unmanned mine
truck, a terminal, equipment, a medium and a
chip, and relates to the field of
vehicle control. The method comprises the following steps: acquiring load information of the unmanned mine
truck, and calculating a load compensation
gain coefficient based on the load information; acquiring road
pitch angle information and target acceleration, target speed and current speed of the unmanned mine
truck, and calculating an adaptive feedforward control instruction value based on the road
pitch angle information, the target acceleration, the target speed, the current speed and the load compensation
gain coefficient; calculating a preview vehicle speed and a speed preview error of the preview vehicle speed based on the current speed and current acceleration of the unmanned mine truck; calculating a
feedback control instruction value based on the speed preview error and the load compensation
gain coefficient; obtaining a controller output instruction value based on the adaptive feedforward control instruction value and the
feedback control instruction value; and converting the controller output instruction value into a
throttle opening degree instruction or a
brake pedal opening degree instruction to perform longitudinal control on the unmanned mine truck.
